Altcoins, Tokens and What Separates Them
What You'll Learn
- What "altcoin" means as a category
- The practical difference between a coin and a token
- Why so many tokens can exist on a single network like Ethereum
The Big Idea
You may be wondering what people mean when they say "altcoin." It simply means any cryptocurrency other than Bitcoin. But inside that huge category, there is an important technical distinction I want to teach you: the difference between a coin, which has its own independent blockchain, and a token, which is built on top of somebody else's.
Let's Break It Down
A coin, like bitcoin or ether, is native to its own blockchain. It is the asset that specific network was built around, and it is what pays for using that network. A coin requires an entire independent network to exist.
A token works differently. It does not need its own blockchain at all. Instead, it is created using a smart contract deployed on an existing platform — most commonly Ethereum, which you just learned about. Tokens follow a shared technical standard, so wallets and exchanges know how to handle them consistently. This is exactly why thousands of different tokens can all exist on Ethereum, without each one needing its own separate network.
This distinction explains something important: launching a new token is far more common than launching a new coin. Creating a token is closer to deploying a small program on infrastructure that already exists. Launching a new coin means building and securing an entire independent network from scratch, with all of the challenges you learned about in the mining and Proof of Work lessons.
Real Example
Let me give you a comparison. Think of a coin's blockchain as a country with its own currency. A token is like a business operating inside that country, using its existing banking system. The business does not need to build its own currency or its own banking infrastructure — it simply follows the country's existing rules and plugs into what is already there.
Why It Matters
Here is a practical habit I want you to build: whenever you see a new crypto project, ask yourself, "Is this a coin with its own chain, or a token on someone else's chain?" That single question tells you a great deal about its infrastructure, and what it depends on to keep functioning.
Common Mistake
Many people use "coin" and "token" interchangeably in casual conversation. I want you to know they describe genuinely different technical setups, and that distinction becomes important once you start looking closely at how a specific asset actually works.

Key Takeaways
- "Altcoin" refers to any cryptocurrency other than Bitcoin.
- A coin has its own independent blockchain; a token is deployed on top of an existing one.
- Tokens are more common than new coins because they don't require building and securing an entirely new network.
